The difference between normally open solenoid valve and normally closed solenoid valve
Fault phenomenon one: the solenoid valve does not work after electrification
Today we talk about the refrigeration system of three control valves, they are: evaporative pressure control valve, condensing pressure control valve, suction pressure control valve. They can optimize the performance of the refrigeration system, in the refrigeration system these valves are of great significance.
In air-conditioning and refrigeration systems, liquid refrigerants are usually installed in the liquid line, through a transparent wide-angle lens to observe the refrigerant liquid level and flow conditions, through the lens center indicator color changes, check the water content in the refrigerant.
In the air conditioning refrigeration system, the throttle device is one of the four basic components of the compression refrigeration system, which can reduce the high-pressure liquid from the condenser to the low-pressure liquid, and adjust the refrigerant flow into the evaporator.
In the air-conditioning heat pump system, the four-way valve changes the refrigerant flow direction in winter and summer to switch the refrigeration and heating modes of the system.
